Fully certified and locally owned, Square One Radon offers full service radon testing, radon mitigation, crawlspace encapsulation, and new construction radon services. Square One stands apart from the competition by utilizing the most scientific and calculated approaches to providing radon testing and mitigation solutions. Precise measurements to determine and document air flow, air pressure, pressure field extension, and more are routine practice at Square One. Unfortunately, many radon companies do not invest in the tools, training and techniques required to provide the most effective and efficient solutions to radon problems. Square One Radon was founded with the ideal of offering some of the most advanced, reliable, and proven testing and mitigation technologies in an affordable and practical solution for homeowners, businesses, schools, and other clients. Rob Hartop, Owner and Founder, brings eight years of experience in the radon industry to the Western Slope of Colorado along with his NRPP certifications in both radon testing and radon mitigation. Rob is also a member of the American Association of Radon Scientists and Technologists (AARST), spent over 12 years working in customer relations, has over four years experience in automotive and industrial fluid line fabrication, and holds a Bachelor of Business Adminnistration with concentrations in finance and economics.

"Square One Radon was professional, knowledgeable, reasonably priced, prompt, and did a beautiful job. The company's owner, Rob is the best. I would recommend his company enthusiastically and without any reservations. I'm a retired consumer-protection lawyer, so I know an outstanding company when I see one."

Additional DBA - Renewal by Andersen, an Andersen Company.

"We bought an older home and several windows were letting in the winter draft. We decided this past year to have the windows replaced. From the consultation appointment to installation this company was completely professional. We did not feel forced into buying and the installers did an exceptional job. Our house stayed much warmer this winter. We will be using Renewal again!"

FAQs for mold & toxic material test projects in Grand Junction, CO

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
